MSE-LD20HR Laser Distance Measurement Sensor for Measuring off Hot Seamless Rolled Steel Rings from 600°C (1112°F) to 1200°C (2192°F)

Additional Technical Information

The MSE-LD20HR Laser Distance Measurement Sensor is extremely versatile and can be programmed to operate in various distance measurements modes either remotely controlled or automatically, using a PC or a host computer or as a stand alone microprocessor device. The MSE-LD20HR is provided with LDMTool PC software that allows the user to communicate with the laser via a serial link and to set the lasers various parameters.

Distance measurement of the MSE-LD20-HR can be controlled in these various modes of operation:

1. Manually with a PC using HyperTerminal, a terminal emulation program or the provided LDMTool software via the RS232 or the optional RS422/RS485 serial interface

2. Manually by transmitting ASCII characters via the RS232 or the optional RS422 or optional RS485 serial interface from a PLC, a PC, a host computer or a stand alone microprocessor device.

3. Automatically as a stand alone device and programmed to start in the AutoStart mode.

4. Continuously by selecting distance tracking mode

5. Remotely controlled by using the external trigger

6. Remotely controlled via the serial interface

Distance measurement can be monitored in different ways:

1. Using the 4 - 20 mA Analog Output

2. Data transfer using the RS232 serial interface

3. Data transfer using the optional RS422 or optional RS485 serial interface

4. Data transfer using the optional ProfiBus, Profinet or the Ethernet TCP/IP FieldBus Interface.

Optional ancillary equipment include an external ProfiBus DP Gateway Interface Box, an external ProfiBus DP interface box, an external ProfiNet interface box, an external DeviceNet interface box, an external Ethernet TCP/IP interface box, an external Ethernet/IP Interface box, various Junction Boxes, and AC to DC Power Supplies. Also available is an HMI/Controller that allows connection and communication with one (1) or two (2) MSE-LD20HR Laser Distance Measurement Sensors for programming and displaying of distance measurement, length measurement, product presence. or product position, and with (2) lasers connected can be used to calculate and display the width, length or thickness of hot or cold product.

The MSE-LD20HR Laser Distance Measurement Sensor operates up to a 20m ((65.6 ft) range off static or passing hot steel seamless rolled ring in difficult areas and in harsh hazardous environments. The MSE-LD20HR measures distances off of hot natural surfaces that are as hot as 1200°C (2192°F).
